Dengue Fever: Causes, Effects, Distribution and Prevention


Dengue fever is a disease caused by a family of viruses which are transmitted by aedes Aegypti mosquitoes. It is found in the urban areas of tropical countries. Generally an infection of Dengue fever lasts around 6-7 days with a small peak of fever towards the end of the 7 days. Because it is caused by multiple viruses, you can be immune to 1 type of dengue fever but still get another type. If you get dengue fever you could also get Dengue shock syndrome which can further weaken your body.

The definition of dengue fever has been in use since 1975; all five criteria must be fulfilled:
  1. Fever, bladder problem, constant headaches, severe dizziness and loss of appetite.
  2. Hemorrhagic tendencys (spontaneous bruising, bleeding from mucus, gingiva, injection sites, etc.; vomiting blood, or bloody diarrhea)
  3. Thrombocytopenia (loss of platelets, means if you bleed, you cant repair yourself)
  4. Evidence of plasma leakage
  5. Encephalitic occurences.
Dengue shock syndrome is defined as dengue fever plus:
  • Weak rapid pulse,
  • Narrow pulse pressure
  • Cold, clammy skin and restlessness.
